I have gotton this "ToolBox.exe has failed" when installing the latest TeeChart. I just ignored it and everything seems to be working fine so far.

It turned out my X Values were not sorted. That answers that.

But then why are the X values auto sorted from lowest to highest values when I use the Assign method but not the Add?

I have two graphs. When I use TGraph1.Series(0).Add(arrayTimeX, arrayDistanceY) it seems to be a crap shoot if the series will be drawn correctly. But if I copy that graph to another graph, using TGraph2.Series(0).AssignValues(TGraph1.Chart.Series(0)) the series is always drawn correctly even though...
